Title: Several bugfixes / documented but missing features in Image class

I made a few fixes in Image and Drivers classes, nothing new, just what should be.

Added docblocks to Image::reload()
Changed visibility of image drivers vars to protected, allowing extensions/plugins
Added real support to JPEG quality to Imagemagick and Imagick drivers
Removed a duplicated checking on exec command in ImageMagick::exec()
Removed unused var in ImageMagick::exec()
Improved create_color code (all drivers uses the same function, why this was written 3 times?)
Little fix on Imagick::add_background: it was suposed to add a bg only if bgcolor is set (like other drivers)
Fixed a mispell in Imagic::create_color docblock
